High-strength nylon core string

Abstract

A high-strength nylon core string comprises a nylon core, a winding wire spirally wound on the nylon core and a bead head arranged at one end of the nylon core, one end of the nylon core winds around the bead head and then is spirally wound with the bead head to form a closing opening, and a first reinforcing layer formed in a silk thread winding mode is arranged at the closing opening. The first reinforcing layer is additionally arranged at the closing-up part, so that the hardness and the strength of the closing-up part can be enhanced; the diameter of a ring formed at the end part of the nylon core can be shrunk by the silk threads of the first reinforcing layer, so that the bead head can be tightened by the ring, the position of the bead head is basically fixed, and threading of the bead head is facilitated; after the nylon core closing position is fixed, the nylon core closing position is not easy to break, and the service life of the string is prolonged.

Description

TECHNICAL FIELD

[0001] The utility model relates to musical instrument accessory technical field especially a high strength nylon core string. BACKGROUND

[0002] As Figure 1 The traditional nylon core string includes a nylon core, a winding wire 1 spirally wound on the nylon core, and a bead 3 arranged at one end of the nylon core. One end of the nylon core is wound around the bead and spirally wound with itself to form a closing opening 2. The winding wire 1 does not completely cover the closing opening 2, and the nylon at the closing opening 2 is exposed. Therefore, the string is relatively soft and fragile at the closing opening 2, which is not conducive to threading the bead 3, and the string often breaks at the closing opening 2. SUMMARY

[0003] The utility model solves the technical problem of providing a high-strength nylon core string, improving the strength of the closing opening of the nylon core, improving the installation efficiency of the string, and prolonging the service life of the string.

[0004] To solve the above technical problems, the technical scheme of the utility model is as follows: a high-strength nylon core string includes a nylon core, a winding wire spirally wound on the nylon core, and a bead arranged at one end of the nylon core. One end of the nylon core is wound around the bead and spirally wound with itself to form a closing opening. A first reinforcing layer formed by silk winding is arranged at the closing opening. The utility model principle: adding a first reinforcing layer at the closing opening can strengthen the hardness and strength of the place; the silk of the first reinforcing layer can shrink the diameter of the loop formed at the end of the nylon core, so that the loop can tightly hold the bead, the position of the bead is basically fixed, and threading the bead is facilitated; after the closing opening position of the nylon core is fixed, the place is not prone to breaking, prolonging the service life of the string.

[0005] As an improvement, a second reinforcing layer formed by silk winding is arranged on the first reinforcing layer.

[0006] As an improvement, the silk is a nylon thread.

[0007] As an improvement, the loop formed at one end of the nylon core tightly holds the bead.

[0008] As an improvement, one end of the winding wire covers the end of the closing opening.

[0009] The utility model compared with prior art brings the beneficial effect that:

[0010] Adding a first reinforcing layer at the closing opening can strengthen the hardness and strength of the place; the silk of the first reinforcing layer can shrink the diameter of the loop formed at the end of the nylon core, so that the loop can tightly hold the bead, the position of the bead is basically fixed, and threading the bead is facilitated; after the closing opening position of the nylon core is fixed, the place is not prone to breaking, prolonging the service life of the string. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 2 Bead end of the utility model. DETAILED DESCRIPTION

[0013] The utility model will be further described below in conjunction with the drawings of the specification.

[0014] As Figure 2 shown, a high-strength nylon core string comprises a nylon core, a winding 1 spirally wound on the nylon core, and a bead 3 provided at one end of the nylon core. One end of the nylon core is wound around the bead 3 and spirally wound with itself to form a closed end 2. The closed end 2 of the nylon core forms a loop and covers the bead 3. One end of the winding 1 covers the end of the closed end 2, and the remaining part of the closed end 2 is exposed outside the winding 1. The length of the closed end 2 between the winding 1 and the bead 3 is about 1-1.5 cm. A first reinforcing layer 4 formed by silk winding is provided at the closed end 2. One end of the first reinforcing layer 4 is close to the bead 3, and the other end of the first reinforcing layer 4 extends to the winding 1. A second reinforcing layer 5 formed by silk winding is provided on the first reinforcing layer 4. The second reinforcing layer 5 is colored for easy identification. The silk is nylon thread.

[0015] Principle of the utility model: the first reinforcing layer and the second reinforcing layer are added at the closed end 2 to strengthen the hardness and strength of the closed end 2. The silk of the first reinforcing layer can contract the diameter of the loop formed by the end of the nylon core, so that the loop can tightly hold the bead 3, and the position of the bead 3 is basically fixed, which facilitates threading of the bead 3. After the closed end 2 of the nylon core is fixed, the closed end 2 is not easy to break, which prolongs the service life of the string.

Claims
